MACHINE FOR OR NAMENTING BED-PLATES'FOR CASTING SHEET-GLASS.

SPECIFICATION forming part of Letters Patent No. 507,572, dated October31, 1893.

Application filed March 7, 1893; Serial Nn- 464,952. (No model.)

To all whom it may concern:

Be it known that I, EDWARD WALSH, J12, a citizen of the United States,residing in the city of St. Louis, State of Missouri, have invented acertain new and useful Machine for Ornamenting Bed-Plates for CastingSheet- Glass, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart of this specification, wherein like symbols refer to like partswherever they occur, and in which- Figure l is a front elevational Viewof my improved machine. Fig. 2 is a perspective view of a preferred formof knu rling wheel to be used in connection with my machine. Fig. 3 is adiametrical longitudinal section of the knurl wheel. Fig. 4 is a crosssection of the same. Fig. 5 is a plan view of a portion of the finishedbed plate. Fig. 6 isadetail view, showing in section, a portion of thebed plate and the knurl wheel in operative contact therewith.

My invention relates to a new. and useful improvement in machines forornamenting bed plates for casting sheet glass, and consists, generallystated, in an apparatus of the kind described, in which a knurl wheel ismounted so as to contact with the surface of the bed plate, and in themeans for giving to the knurl wheel, a longitudinal and lateral movementrelative to the bed plate. ThisI accomplish by the construction shown inthe accompanying drawings, in which, A represents a longitudinallymovable bed plate of a bed planer of any approved construction, in whichthe back, or return movement of the bed, is preferably effected at thesame speed as the forward movement.

B represents the body of the frame work of the planer, in which areformed guide ways for the longitudinally movable bed plate A. Extendingupwardly from each side of this body portion B, are standards 0 whichsupport a vertically movable cross piece D. Slidingly mounted on thiscross piece D, is a head stock E which carries, in a suitable manner, aknurl wheel G.

F represents suitable driving mechanism for the bed plate A, through themedium of which its reciprocating movement is effected.

H represents the bed plate of the casting table which is to be operatedupon by the knurl wheel, which casting table is secured by suitableclamps to the reciprocating planer bed plate.

The operation of the apparatus in configuring the casting table H, maybe described as followsz Suitable power being applied through thepulleys F, the bed plate A will be given a reciprocating longitudinalmovement, and carry with it the casting table H. The cross piece D isthen lowered until the knurl wheel carried by the head stock E willcontact with the surface of the casting table. contact will be veryslight, until the knurl wheel has made a distinct path upon the surfaceof the casting table, when the cross piece will be gradually lowereduntil the desired depth has been formed in the table, which is beingcontinually carried back and forth under the action of the wheel. Aftera path of sufficient depth has been formed, the cross piece is raised totake the knurl wheel outof contact with the table, and the head stock Eis adjusted laterally, so that this second path of the knurl wheel willslightly overlap that previously formed. The knurl wheel is againlowered to form this second path, which is preferably of a depthcorresponding with the one first formed. This cycle of operations iscontinued until the desired area of surface on the casting table isconfigured with the converse of the design on the knurl wheel.

In the drawings,Ihaveillustratedapeculiar form of design for a knurlwheel which is especially adapted for machines such as herein shown anddescribed, which knurl wheel is formed with symmetrically duplicatedcircumferential edges, and an irregular design in the middle portion ofthe periphery. By such a design I am enabled to start a new path at anypoint on the periphery of the wheel, care At first, this only beingrequired to correctly set the wheel so that the raised and reducedportions of the adjacent paths shall register. In this mahner, thedesign maybe such that it is not re peated transversely of the castingtable, which is of special advantage in the manufacture ofglass from atable so configured, from the fact that glass of such ornamentation hasspecial commercial worth.

Having thus described my invention, What I claim, and desire to secureby LettersPatent, is

In an apparatus for oruamenting glass cast- 5 ing tables,the combinationwith a knurl wheel,

of a. support for the casting table, and means for forcing the knurlwheel'into contact with the surface of the casting table, and giving tothe knurl wheel a longitudinal and lateral movement relative to thecasting table, sub- 10 stantiatlly as described.

In testimony whereof I hereunto afifix my signature, in presence of twowitnesses, this 23d day of February, 1893.
